From fc4aaba8a3b8fe7815e103cc20f2a36d5de7e8ab Mon Sep 17 00:00:00 2001
From: Keith Packard <keithp@keithp.com>

Subject: [PATCH] Remove use of include_next from c++ headers
Using include_next bypasses the default header search path and lets
files later in the include path take priority over earlier files.
This makes replacing libc impossible as the default libc headers will
occur after the libstdc++ headers, and so be picked up in place of
headers inserted at the begining of the search path or appended to the
end of the search path.
Using include_next is a hack to work-around broken combinations of
libraries, and is not necessary in a well constructed toolchain.

Subject: [PATCH] Allow default libc to be specified to configure
The default C library is normally computed based on the target
triplet. However, for embedded systems, it can be useful to leave the
triplet alone while changing which C library is used by default. Other
C libraries may still be available on the system so the compiler and
can be used by specifying suitable include and library paths at build
time.
If an unknown --with-default-libc= value is provided, emit an error
and stop.

From fd6aa8e67aec185b0d84ba9551fd38c90c9d6d8a Mon Sep 17 00:00:00 2001
From: Keith Packard <keithp@keithp.com>
Date: Fri, 26 Aug 2022 14:30:03 -0700
Subject: [PATCH] driver: Extend 'getenv' function to allow default value
Right now, a missing environment variable provided to the 'getenv'
function in a .specs file causes a fatal error. That makes writing a
spec file that uses the GCC_EXEC_PREFIX value difficult as that
variable is only set when the driver has been relocated, but not when
run from the defined location. This makes building a relocatable
toolchain difficult to extend to other ancilary pieces which use specs
files to locate header and library files adjacent to the toolchain.
This patch adds an optional third argument to the getenv function that
can be used to fall back to the standard installation path when the
driver hasn't set GCC_EXEC_PREFIX in the environment.
For example, if an alternate C library is installed in
${prefix}/extra, then this change allows the specs file to locate that
relative to the gcc directory, if gcc is located in the original
installation directory (which would leave GCC_EXEC_PREFIX unset), or
if the gcc tree has been moved to a different location (where gcc
would set GCC_EXEC_PREFIX itself):
*cpp:
-isystem %:getenv(GCC_EXEC_PREFIX ../../extra/include ${prefix}/extra/include)
I considered changing the behavior of either the %R sequence so that
it had a defined behavior when there was no sysroot defined, or making
the driver always set the GCC_EXEC_PREFIX environment variable and
decided that the approach of adding functionality to getenv where it
was previously invalid would cause the least potential for affecting
existing usage.

Subject: [PATCH] gcc: Allow g++ to work differently from gcc
Compile gcc.cc with -DIN_GPP defined when building g++ so that the
code can respond appropriately for the default target language. This
allows the driver to customize the specs used, selecting different
linker scripts, adjusting the use of crtbegin.o/crtend.o etc.
By default, this change has no effect; targets need to explicitly
check for IN_GPP to have alternate behavior.

Subject: [PATCH] picolibc: Add custom spec file fragments for using
picolibc
The '--oslib=' option allows targets to insert an OS library after the
C library in the LIB_PATH spec file fragment. This library maps a few
POSIX APIs used by picolibc to underlying system capabilities.
The '--crt0=' option allows targets to use an alternate crt0 in place
of the usual one as provided by Picolibc.
For example, picolibc provides 'libsemihost' and 'crt0-semihost.o' on
various targets which maps some POSIX APIs to semihosting capabilities
and signals the semihosting environment when 'main' returns. These
would be used by specifying --oslib=semihost --crt0=semihost.
This patch also takes advantage of the IN_GPP conditional when
building g++ to elide exception handling contents from the executable
when not linking with the g++ driver.
